Patent TW-I744728-B (TW)
Title: Sram-based process in memory system
Inventor: ZHANG ZHENGYA
IPC: G06F7/523
Filed: 2019-11-28
Granted: 2021-11-01
Abstract: Many signal processing, machine learning and scientific computing applications require a large number of multiply-accumulate (MAC) operations. This type of operation is demanding in both computation and memory. Process in memory has been proposed as a new technique that computes directly on a large array of data in place, to eliminate expensive data movement overhead. To enable parallel multi-bit MAC operations, both 
width- and level- modulating memory word lines are applied. To improve performance and provide tolerance against process-voltage-temperature variations, a delay-locked loop is used to generate fine unit pulses for driving memory word lines and a dual-ramp Single-slope ADC is used to convert bit line outputs. The concept is prototyped in a 180nm CMOS test chip made of four 320x64 compute-SRAMs, each supporting 128x parallel 5bx5b MACs with 32 5b output ADCs and consuming 16.6 mW at 200MHz.

Title: Instrument for examining a gemstone
Inventor: LAWSON SIMON C
IPC: G01N/
Filed: 2003-01-17
Abstract: The instrument has a housing (1) mounting the following components to provide a self-contained, stand-alone instrument; a compact solid state 532nm laser 9 coupled to a window (5) in a thermally-insulated container (2) for liquid nitrogen and the gemstone (4); a compact solid state diode 655 nm laser (10) coupled to the window (5); two compact, sensitive CCD spectrometers 11<a> and 11<b> detecting luminescence features with zero-phonon lines at in the range 550-1000 nm; a processor (17) for processing the signals from the spectrometers 11<a> and 11<b> to indicate whether the gemstone (4) is a natural diamond which has not been subjected to irradiation treatment or hgih-pressure high-temperature treatment; and a display (18). The container (2) has a cover (6) and a pin (8) which is used to place and hold the gemstone (4) against the window (5).

Abstract: Isolated nucleic acid (I) that encodes any of 50 amino acid sequences (II) that have, at specific positions, an amino acid (aa) alteration. The specification includes (i) a table identifying the function of (II) and the nature/position of the amino acid exchange and (ii) sequences for (I) and (II). Independent claims are also included for the following: (1) vector that contains at least one (I); (2) host cell transfected with at least one vector of component (1); and (3) preparing fine chemicals by culturing cells of component (2).
